Anubias and java fern both have the advantage of not even needing substrate - it's easier to simply tie them to something. :) If you do plant them in the gravel, you have to be super careful not to bury the rhizome, or the plant will die (which is why I never plant them because I can never tell if I have buried it or not.
I love java fern. Attached is a picture of my tank, which is absolutely overgrown with the stuff. All of it is either tied to driftwood or growing out of other bits of fern. I do nothing to help it. As you can see, it's super easy. :) There is some anubias in there too, but I suspect it's under the java fern, just like everything else.
